INSTALLING THE ADVANTAGE! IN A 256K AT
If you are installing your Advantage! in an AT equipped with a
256K system board, please note the following:
- An Advantage! being used in a 256K AT MUST be configured for
the Split Memory Addressing mode of operation. Figure 3-4 in
the Advantage! User's Manual shows the correct switch
settings for Switch Block #3 on the Advantage! in a 256K AT.
(In a 512K AT, you may use either Split or Contiguous Memory
Addressing on the Advantage!)
- The AT system board may be equipped with either 256K or 512K
installed. A jumper on the system board (J18) determines the
maximum amount of memory the system board will accept. With
the jumper in one position, the system board will accept a
maximum of 256K, while in the opposite position, the system
board will accept a maximum of 512K. IBM ships some 256K ATs
with this jumper in the 512K position. This means that in
such a 256K AT, there is an additional "phantom" 256K memory
block present. When the Advantage! is then installed, its
memory will conflict with this "phantom" 256K block on the AT
system board. The usual symptom of this problem is an error
during power on self test such as "040002...201".
- To avoid this memory addressing conflict, before you install
the Advantage! in a 256K AT, verify that the jumper on the AT
system board is in the correct 256K position. The jumper is
identified as "J18" and is located underneath the disk
controller card at the very front of the AT chassis. It may
be necessary to lift the disk controller card up in order to
gain access to the jumper.

RUNNING THE AT SETUP PROGRAM
- When running the "SETUP" program to tell the AT how much
memory is installed in the 640K base memory area, the screen
display indicates that the only valid responses are 256, 512
or 640. Although not indicated by the display, you may also
enter 384 if that is appropriate for your machine.
- Likewise, when telling the AT how much extended memory you
have, the screen display indicates that the only valid
responses are 0, 512, 1024, etc. Although not indicated by
the display, you may enter any value falling on a 128K
boundary, e.g. 0, 128, 256, 384, etc., up to 15360 (15
megabytes).
